To all whom it may concern:

Be it known that I, CHARLES E. SMITH, a citizen of theUnited States, andresident of the borough of Brooklyn, city of New 5 York,';in the countyof Kings and State of New York, have invented certain new and 4 usefulImprovements in Typewriting Machines, of which the following isaspecifi' cation. r v My invention relates to typewriting machines andmore particularly to means for 1, ensuring that the machine is in propercondition to be received withinfits inelosing case before the case is.closed. To the above and other ends whichwill hereinafter appear, my,invention consists in the features of construction, arrange-v ments ofvparts,and combinations of devices set forth in the followingdescriptionand particularly pointed out in the appended claims. y i J In thedrawings, wherein like reference characters indicate corresponding partsin the different views, 1

V v ,Iiigure 5 is a like view of the'same showing alsothe shift lock key depressed, and,

the parts locked in shifted position. y In all of the views I haveomitted parts of the machine unnecessary to an understanding of myinventionin its embodiment therein. p a H V v .My invention relates moreparticularly to light portable machines and is shown in the presentinstance embodied in a Remington-portablemachine-which in many respects.is; like the machines shown in the following patents: A; W, Smith,1,342,518,"

June 8, 1920; J. BLITOlden, 1,386,256, Aug. 2,1921; In theRemington-portable machine the carriage is supported against movementfrom its normal or lower-case position by the cover of the inclosingcase when the latter is closed. This prevents the carriage fromrshiftingbackward and forward when the machine is being transported in its case,thus preventing injury to the machine which might result from suchshifting ,of the carriage. If, however, the, operator should leave thecarriage locked in its shifted position, it would interfere with andprevent the cover frombeing closed." Any forcible attempt to close thecover at this time might result in injury to the machine or to thecover, or both., a,

By my invention I overcome this difliculty and ensure the proper returnof the carriage to normal position before the cover I isfclosed, andthereafter render the case shift locking means ineffective so long asthe machine is" in condition to be inclosed within its casing. The actof. expanding the machine, or rendering it in condition for'use, iseffective to automatically withdrawithe means by which thecase shiftlock- 1 mg means are rendered ineffective, so that such locking meansare again in condition for use.

Theframe of'the machine comprises an outer sheet metal frame 1 and aninner $5 sheet metal frame 2 attached to the frame 1 and by which thevarious working parts of the machine are supported. A series ofsegmentally arranged type bars 3 are mounted in guide'slots of a typebar segment 4, 99

secured to the inner frame 2 and carrying a pivot wire 5 on which thetype-bars are mounted. Eachtype barhas a heel with segmentally arrangedgear teeth 6, 'with V which similar teeth 7 on a companion subleverS areadapted to mesh. The sub-levers 8 are pivoted on a pivot wire 9 carriedby a suitably'fixed slotted support or segment,

not shown. The forward end of each sub-' lever 8, is pivoted to adepending link 10 100 which vin turn is pivoted to a second subl ever11- jfulcrumed at its forward end on a sheet, metal combined guide combandfulcrum plate, designated as a whole by the reference numeral12. Thisplate is secured in place at its ends by screws 13and 14 that arereceived in tapped openings in ears 15 and 16, respectively, on the sideplates of the inner frame 2. Each sub-lever 11 is connected to adepending link 17 which in turn; is connected to a keylever 18, pivotedon a pivotwire 19. The rear end of each key lever is guided by and heldon its pivot by a guide comb 20 which supports the pivot wire on a fixedpart of the machine,

whereas the forward end portion of each key lever extends through aguide slot 21 in the'forward guide comb 12. V

. The type bars are adapted to be turned on their pivot wire 5 from theinoperative position, shown in Fig. 1, where they remain collapsedrelatively to the remainder of the machine on a fixed t 3e rest a to the0 3era- J 7 tive position, or position of use, indicated in Fig. 2.Tnthis last mentioned position the type bars are expanded upwardly fromthe body of the machine, and each is in a posi tion to be movedrearwardly and clownwardly to the printing position, and to strikeagainst the top of a platen 22, when the com panion printing key isdepressed to actuate its lever 18. The hand actuated means, 0p-

erable at will and by which the type bars are turned from theirinoperative position shown inFig. 1 to their operative position shown inFig. 2, comprises a rock shaft 23 mounted atits ends in the side platesof the inner frame 2. One end portion of the shaft has-tendstransversely across the machine to points near the sides thereof.The frame 28 is formed with depending guide arms 29 that are mounted tomove up and down in companion grooved guides 30, carried by the mountedFfor vertical shifting movement from the Fig. 1fto the Fig. 2 position,and vice versa, carries a segmental pad 31 arranged beneath the typebars, and cooper,-

type barv segment 4. The frame 28 thus ative therewith to control themovements of' the type bars 2L1OllIlCllill6ll pivot toeither of the twopositions shown. Each of the type bars carries a lower case type 32 andan up per case type 33, andin the Remington-portable machine a caseshifting movement of the platen may be effected to bringeither set oftypes into use. In Figs. .1 and'2 it will be seen that a sheet metalcase shift frame e),-

tends fore-and-aft of the machine and comprises side plates 84, Each ofthese plates is pivoted at its forward end, as at, 35, to a dependinglink 36, mounted on a pivot pin 37 projectinginwardly from a side plateof the frame 2, and prevented from accidental detachment from-itspivot'by a cotter pin 38.

The rear-end portion of each plate 3 1 is bent to form a horizontahydisposed flange 39,130

which is-seeured, by screws 40, a casting 41. This casting is pivoted at4:2 to upright crank arms 43, carried by a rock shaft 14, received atits endsin bearing openings in the side plates of the frame 2. Thecasting carries sheet metal grooved tracks45 and46, which receivebearing rollers 47 that also coact with grooved tracks 18 and 49of acarriage bed 50 whichsupports the platen22. The entire carriage, withits platen, is thus supported to travel 'laterally overthesupport orcasting {T1, and'to receive a bodily 'foreand-aft shift mg movement withthe case shift frame, of which the support 41 forms a part. Suitablestops (not shown) areemployed to limit the case shifting movements ofthe parts, and springs .51 return the shifted parts to normal, or lowercase, posit on when they are not held in the uppercase position againstthe force of said springs.

In the present construction, the key actuated means for controlling thecase shifting movements of the, parts, comprises a case shift key lever52'provided with akey 53 and fulcrumed on the pivot wire 19. This keylever is guided at its" forward end portion in a guide slot 54in thecomb plate 12. The lever 52 is connected to an upwardly extendinglink55, which in turn is connected, at 56,

to abell crank lever The lever 57 is pivoted on a pin or support 58which is carried by and projects inwardly from theleft-hand sideplateframe 2. The depending arm of the bell crank 57 extends in front ofapiin 59- which projects inwardly from the left hand side plate 34: ofthe shift frame. The

depending arm of the bell 'cranl'r lever 51 thus transmits a rearwardmovement toithe shift frame and the parts carried therebywhen the shiftkey 53 is depressed. A shift lockkey 60 is carried by. an angular lever61 which is pivotedat 62 to the lever 52, onthe outer side thereof. Thelever 61" has a de- V pending arm which terminates in a hooklikeengaging or looking member or catch63,

preferably offset slightly to theleft of the plane of the main bodyportion of the lever '61, as best shown in Fig. 5. The pivot 62 whichunites the levers 61 and 52 is in the nature of a shouldered screw bolt,secured by a nut 64 to the ,lever 52 and forming-a pivot bearing forthe. lever 61. A- spring 65 is coiled around the shank of the screw boltand has one free end 66 thereof turnedover and bearing against thebottom edge of the lever" 61, its other free end 67 hearing against the7 upper edge of the lever52. The force of this spring is thus exerted toreturn the lever .61 on its pivot62 to the Fig.1 pos tion and tonormally maintain it relatively to the lever 52 in the position shown inthis figure.

lug 68 formed on'and extending laterally from the lower edge of thelever 61pro eets under the lever 52, and. coacts therewith" to limit thereturn movement of the lever 61 relatively to the lever 52. I r

A sheet metal locking platefor member 69- is secured in front of thecomb plate 12 at the left-hand end-thereof, as best shown fore-and-aftof the, machine,by forcing it rearwardly or allowing it to springforwardly under control of the left-hand screw 14. Thus this screw is inthe nature of a headed screw, the shank of which passes through anopening in the lower endportion of the member 69 and effects afore-and-aft adjustment of the lower end of the locking member or plate69. It will be seen that this plate is mounted to the left'ofthe slot 54in the comb plate 12, and that its-lower engaging edge 71 extends belowand forward of the lower edge ofthe comb plate. I Pres sure applieddirectly to the shift lock key will first. turn the lever 61 on itspivot 62 until the hook-like end 63 of said leverbears against the frontfaceof the plate69. Since the lever 61 can turn no further at this time,the pressure exerted onthe key 60 will carry the key lever 52 down withit until the bill of the hook reaches theedge 71 of the plate. The hookwill then be forced beneath said edge, and; engaging the latter willprevent a return. movement of the lever 61,"shift' lever 52 and theparts controlled thereby; and will lock the carriage in its case shiftedposition. In order to release the locking lever 61 and enable the partsto return to normal position, it is merely necessary, with the partsthus far described, to depress the shift key, 53. This relieves theengaging pressure exerted by the bill of the hook against the edge 71 ofthe locking plate. The lever 61 being thus freed from further 7restraint willbe returned by its spring 65 to normalposition relativelyto the lever 52. This results inwithdrawing the bill .of the hookfrom-beneath the edge 71 of the lockingrplate, and whenpressure of theopera ators finger is released from the depressed shift key 53, the keylever 52 and the parts controlled-thereby are returned to normalposition by thereturning springs 51. 1

v The Remington-portable machine is provided with a carrying caseinwhichthemachine may be inclosed before-transporting it. The inclosing caseincludes a baseboard 72, on which the machine is fixedly secured, if

and a detachable cover 73 having arearwall 7 1.:- Rearwardly projectingfingers are securedto the baseboard and are adaptedto enter openings 76in plates 77 secured to the backwall 76L of the cover. When the ma-.chine is collapsed, the carriage properly centered, and in normal, orlower. case position, the cover maybe alinedv withthe baseboard in therear thereof, with the projeo' tions extending into the openings 76. Thecover may thenbe given a pivotal movement on said projections resultingin swing ing the coverforward and down around the rear edge of thebaseboard to inclose the machine. The rear wall 74: of the cover, asusual, is provided with contacts 78,; which in the presentinstanoe, arein the nature of rubber blocks secured to and projectinginwardly fromthe wall 7 4, near each side wall. These contacts are alined with theend plates 7 9 of the carriage when the latter is centered on themachine. Thepurpose of these contacts is to bear against the end plates79 of the carriage when the cover is closed, and support the weight ofthe*.car-.

riage in normal. or lower case position, and i prevent the carriage fromshifting from said position while the machine-is being carried 7' in thecase, rear end lowermost. This pre vents the-carriage from shiftingbackand forth while the machine is being transported in its case, andprevents theresultant' injury to the machine that might follow from suchshifting movement of the carriage, However, it will be understood, froma-conslderation of Figs. 1 and 2, that if the oper: ator should: leavethe case. shifting mechas nism locked, asindicated in Fig. 2, the car-.

riage would be held in its'rearmostkshifted position, increasing. thelengthwise: dimen 'sions ofthe machine at" this point. This.

would. result in the rear ends of the. plates 79 of thecarriage beingmaintained in the pathof the projections 7 S on the cover,andpreventvthe cover from being closedh The use of, any considerableforce.to close the cover at this time'might result in injury to the machine,or to the cover, or to both.

The featuresrthus far described were'not invented by me. The purpose ofmy present nvention in the main is to overcome the difiiculty pointedout above, and render it impossible to injurethe machine or its cover,

by providing automatically. operating means,

for releasing the case shift locking means preliminary vto inclosing themachine, and thereafter renderthe ease shift lock inefl'ee? tive untilsuch time as the machine is again in condition for use. It will ofcourse be understood. that it is necessary tocollapse the machine beforeitcan beinclosed in its case. In-thepresent instanceI utilize the meansfor collapsing the machine to auto matically effect a release of thecase shift buckle 83; This enables thefparts of" the to lengthen orshorten the link.

link to beadjusted relatively to each other The for ward'end of the link82 is pivoted at 84 to areleasing or controlling member 85,- pivoted at86 on a sheet metal angular bracket 87,

se'curedin place by any suitable means. In

the present instance I secure the bracket in place with theaid of theleft-hand screw 14 and: a nut 88. This member 85- extends through andworks in the slot 541111116 comb plate 12, and has a cam face 89 and aconl the member 85 works in the slot 54, and is V to the right andbeneath the key lever 52.:

tact 90; It'will be understood that this member 85 turns on its pivot ina fore-andaft plane, and'in a plane coincident with the plane of thecase shift key lever 52. While supported and guided by the side wallsthereof, it is nevertheless situated at a point which'is low enough toprevent it from in.

terfering withthe operation of the key lever.

52 which works inthe same slot. The plane of'the lever 61 is parallelwith and to the left of the member 85, and lever 61 carries near thelower end of its depending arm a laterally projectingpin 91 extendingtherefrom The position of the pin 9121's such that when 7 the shift lockkey ()0 is depressed and main tained looked, as indicated in Fig.2, saidpin will be in front of the cam 89, and adapted to be acted on therebywhen the cam carrying member is moved from the Fig. 2 to the Fig. 1position. The effect of this movement of the cam face 89 is to effect adownward and forward camming action on the pin" 91, thereby turning thelever 61 on its pivot 62 until the bill of the hook is freed fromthe'edge 71 of the locking plate.

The spring 65 is then immediately effective to restore the lever 61 tothe'position, it normally bears to the lever 52, and the latter beingfreed from further restraint will, to gether with the parts controlledthereby, re turn to normal position; Theelfectfofthis is that thecarriage will move forward from the Fig. 2 position to that indicated inFig,

. 1, and said carriage will nolonger offer an obstruction to the closingof the cover t i close the machine. 1

hen the hand controlled rock shaft 23,1

and the parts controlled thereby',-are moved from the Figg2 to the Fig;1 position, and 7 result in automatically releasing thecase shiftinglocking means as stated, th emembfer 'will be retained 'in the positionshown in Fig. 1 until the shaft 23 and the parts con-1 trolled therebyare againmoved to restore the machine to the condition of use,shown inFig. 2. The member85 being thusreta-i ned in-the Fig. 1 positionpresents the contact face or edge thereof ina position where it will beinthepath of and coact with the pin 91, toprevent an engagement ofthelocking hook of the lever 61 with the edge 71 of the locking plate.It'follows therefore that if, after the case shift lockisautomaticallyreleased in the manner stated, the operator should againdepress the shift lock key 60, it willbeinefiective to lockthe easeshift mechanism, and it doesnot again become effectiveunti1-theme1nber85 is auto maticallywithdrawn by actuating the shaft 23to place the machine in condition for use, j

as shownin Fig. 2. It will be observed that even ,ifYthe case shiftmechanismbe not locked-in the-upper case position prior to'collapsingthe machine, there isnothing to prevent the operator fromactuating the. case shift mechanism after the machine hasbeencollapsed,but before inclosing itin its case. If the case shiftmechanism could be locked in its shifted position atthis time, and inthe manner indicated, it would prevent the cover from being closed,notwithstanding the 'ma-' chine is collapsed. However, since the member85 'is maintained'in the effective position so long as the machineremainscollapsed, this renders-the locking means ineffective. Iftherefore the operator at this time should depress the shift lock key60, the lock would not engage, and when pressure of the opera torsfinger is released from saidkey the shifted parts will return to normalposition, and the cover may be closed without any injurious result. r

The adjustment of the link 82 enables me to regulate the point ofrelease in the operation of the member 85. and to compensate for anyadjustment of the lower end of'the plate 69 that maybe effected.

In the Remington-portable machine sev eral specifically different formsof case'shifting means and case shift locking means have been employed,the means shown representing' one form-of such mechanism. It should 7 beunderstood however that'the devices of my invention, with possibleslight modification'in the construction and arrangement of the-parts.may be applied to the different forms referred'to.
